To answer this need, Croll Reynolds pioneered the development of the Rotajector, a combined Ejector/Condenser/Liquid Ring Pump high vacuum system. The benefits of this hybrid system combination are:

  • Reliable high vacuum system
  • Designed for use with low pressure steam
  • Reduced steam consumption
  • Designed for low elevation installation
  • Low purchase and operation costs
  • Custom-designed for each application

 Operation: In a typical rotajector, such as the four-stage configuration shown at right, process gases or vapors are drawn into the suction port of the first stage Ejector and compressed by subsequent stages. The condenser cools the gases and condenses the vapors, thus reducing the load to the liquid ring vacuum pump, which serves as the final compression stage. The pump also handles condensate, eliminating the need for a condensate removal pump.

products_vacuumsystems_hybrid_pic2Configurations: Croll Reynolds Rotajector systems are manufactured in up to six-stage configurations and in a wide range of capacities. Design and configuration flexibility makes the Rotajector a highly versatile vacuum system, readily adapted to a variety of process applications.

Chemical Industry: High efficiency Rotajector systems, designed for operation with low pressure steam, are used for process applications including distillation, evacuation, drying, crystallization, evaporation and cooling.

Pharmaceutical Industry: Vacuum drying at a relatively low temperature is critical in many pharmaceutical applications where heat-sensitive compounds are vulnerable to alternative drying methods.

Food Industry: The high vacuum created by a Rotajector results in the flash evaporative cooling of food products – thus preserving flavor, color and freshness without the need for preservatives or flavor enhancing additives. For chilling just-cooked foods, Rotajectors offer the advantage of using the same low pressure steam source that is used for cooking.
